NOTES:
1.

Unless otherwise noted, all specifications in this table apply to all processor frequencies.

2.

All outputs are open drain.

3.

V

IL

 is defined as the voltage range at a receiving agent that will be interpreted as a logical 

low value.

4.

V

IH

 is defined as the voltage range at a receiving agent that will be interpreted as a logical 

high value.

PECI is an Intel proprietary one-wire interface that provides a communication channel 

between Intel processors, chipsets, and external thermal monitoring devices. The 

processor contains Digital Thermal Sensors (DTS) distributed throughout die. These 

sensors are implemented as analog-to-digital converters calibrated at the factory for 

reasonable accuracy to provide a digital representation of relative processor 

temperature. PECI provides an interface to relay the highest DTS temperature within a 

die to external management devices for thermal/fan speed control. More detailed 

information may be found in the Platform Environment Control Interface (PECI)
